An official update shouldn't be to far away, but in the mean time, if you feel adventurous, you can try out the Particle Build IDE, as it now appears that a working core is finally online!

The Oak Platform for Particle is not completely ready yet - the Oak currently uses the Particle Cloud for uploads and all other cloud features, but is not yet supported in the Particle Web or Desktop IDEs.
Support for the Oak is promised, but no ETA is given.
Please use the Arduino IDE for programming for the time being: arduino
